Scarborough is appearing on the show with his fiancee and co-host Mika Brzezinski.

You can catch the rest of the interview tonight on CBS at 11:35 p.m. ET/PT.

The interview comes after President Trump unleashed a series of tweets last month insulting Scarborough and Brzezinski.

Scarborough was critical of Mr. Trump and Republicans long before the insults. After Mr. Trump fired FBI Director James Comey, for instance, he told Republicans to "stand the hell up" and do something. Scarborough took to Twitter Tuesday night to express his frustration with the GOP.

"It's a shame there are so few Republicans speaking truth to power," he tweeted.
